preenfm2 and preenfm3 / Re: Preen doesn´t start - display is black

« on: March 11, 2019, 12:57:41 AM »

Hi Xavier,
I checked all the points.
Everything is good. I wanted to tell you that I provoked a short circuit while mounting.
I soldered wrongly two points... they were unfortunately soldered together and I didn't notice that.
However, I melt the iron there and they were then fine.
Do you think that could have damaged the display?
Do you have any idea of what it could be now?
Thank you for your help.

Regards,
Maria

Dear Xavier,

thank you so much.
Sorry if it took so long.
Unfortunately I realized that there was a solder point soldered with another one on the display.
I solved that and I could finally see the display on.
The problem is that I cannot read well. The pixel are not all visible :-(

Hi Xavier,

yes, I see the USB key light.
I hear no "pop" when I plug the preen.
I see no content of the USB from my laptop.
I tried to press and hold the buttons you mentioned and so on... but nothing happens.
I send you better pics.

Hi Xavier,
Thank you so much!
I wasn't sure if I had to put a resistor there.
So, I have done it now. However, nothing happens :-(
USB is recognized. I see its light on. But display is still black.

Dear all,

I need your help.
I just finished building my new PreenFM2 (R5d).
Unfortunately, the screen is black. I am using the USB cable connected to the PC. The PC recognizes the USB stick.
But the display is black. Nothing happens.
Attached you will find the pic of my board. Maybe I did a mistake in soldering :-(
Please help me with that.
I am so looking forward to using the instrument.

Thank you!
